Ukushintshashintsha kwe-voltage kumthombo wamandla kuphinde kuthinte i-amp draw - njengoba i-voltage yehla, ukukhuphuka kwamanje ukuze kugcinwe ukuphuma kwamandla okufanayo. Izinga lokushisa lishintsha ukumelana kumakhondakta nezingxenye, kuqhubeke kuhluke ukugeleza kwamanje.

Isici samandla sivela kumasistimu e-AC anemithwalo ye-inductive noma ye-capacitive. Imele umehluko wesigaba phakathi kwe-voltage ne-current. Isici samandla esingaphansi kuka-1.0 sisho ukuthi idivayisi idonsa okwamanje kakhulu kunezibalo ezilula ze-watt/volt eziphakamisa. Ukuze uthole ukudonsa kwe-amp yangempela kumasistimu e-AC anamandla angenamandla: Ama-Amps=Ama-Watts ÷ (Ama-Volts × Power Factor). Amamotho ngokuvamile anezici zamandla azungeze u-0.7-0.85.

Okwamanje "kudonswa" noma "kudonswa" ngumthwalo, akuphushwa umthombo. Umthombo uhlinzeka nge-voltage (ingcindezi kagesi), futhi ukumelana komthwalo kunquma ukuthi kugeleza kangakanani kwamanje. Yingakho igama elithi "amp draw" kunokuba "i-amp push." Umthombo kufanele ukwazi ukuhlinzeka ngesimanje esidingekayo, kodwa umthwalo ulawula ukuthi kugeleza kangakanani ngempela.

Izinhlelo zokusebenza ezisebenza ngebhethri-zizuza ikakhulukazi ekuqondeni ukudonsa kwe-amp, njengoba ukusetshenziswa kwamanje kunquma ngokuqondile isikhathi sokusebenza phakathi kwezindleko. Ukuthi ulinganisa ibhange lebhethri lendlu, ukukhetha amathuluzi kagesi, noma ukuklama isistimu yemoto kagesi, izibalo zamanje ezinembile zakha isisekelo sedizayini ethembekile kagesi.

Ifomula ngokwayo - ama-amps ilingana nama-watts ahlukaniswe ngama-volts - ahlala elula. Ubunkimbinkimbi buvela ekuqondeni ukuthi{3}}izimo zomhlaba zangempela ziwashintsha kanjani amanani etiyetha. I-voltage sag, isici samandla, ukuqala kokusebenza, nokulahlekelwa ukusebenza kahle konke kuthinta ukugeleza kwamanje kwangempela. Ukubalwa kwezimali kwalezi ziguquguqukayo phakathi nesigaba sokuklama kuvimbela izinkinga ngesikhathi sokusebenza.

Izinhlelo zesimanje zokuphatha amabhethri kumabhethri e-lithium ion aphatha okuningi kwalokhu bunzima ngokuzenzakalelayo, aqaphe ukudonsa kwamanje futhi avikele amaseli emonakalweni. Kodwa noma ngama-elekthronikhi asezingeni eliphezulu, ukwazi i-amp draw yesistimu yakho kusiza ukuhlonza izinkinga, ukuhlela ukunwetshwa, nokuthuthukisa ukusebenza kahle.
